IBM C2090-312 Exam Syllabus Topics:

Topic Details Weights
Database Design and Implementation - Design tables and views (columns, data type considerations for large objects, XML, column sequences, user-defined data types, temp tables, clone tables, temporal tables, MQTs, new archive transparency, etc.)
- Explain the different performance implications of identity column, row ID, and sequence column definitions (applications, utilities), hash access
- Design indexes (key structures, type of index, index page structure, index column order, index space, clustering, compression, index on expression, include column)
- Design table spaces (choose a DB2 page size, clustering) and determine space attributes
- Perform partitioning (table partitioning, index partitioning, DPSI, universal table space)
- Normalize data (E-R model, process model) and translate data model into physical model (denormalize tables)
- Implement user-defined integrity rules (referential integrity, user-defined functions & data types, check constraints, triggers)
- Use the appropriate method to alter DB2 objects (table, column, drop column, alter limit key, index, table space, database, online schema)
- Understand impacts of different encoding schemes
Operation and Recovery - Knowledge of commands for normal operational conditions (START, STOP, DISPLAY)
- Knowledge of commands and utility control statements for use in abnormal conditions (RECOVER, RESTART)
- Load and unload data into and from the created tables
- Reorganize objects when necessary (reorg avoidance, automatic mapping table, new reorg features)
- Monitor the object by collecting statistics (run stats, improved in-line statistics, real time stats, autonomic stats, and statistics related stored procedures)
- Monitor and manage threads and utilities (distributed, local, MODIFY DDF)
- Identify and respond to advisory/restrictive statuses on objects
- Identify and perform problem determination (traces and other utilities, plans and packages)
- Perform health checks (check utilities, offline utilities, catalog queries)
- Identify and perform actions that are needed to protect databases from planned and unplanned outages (tables spaces; indexes; full pack; hardware; Flash copies; full, incremental, reference update; copy-to-copy, non-data objects; catalog) and recovery scenarios (off-site recovery, data sharing, table spaces, indexes, roll forward, roll back, current point in time, prior point in time, system point in time copy and restore, catalog and directory, offline utilities (DSN1), new Extended RBA and LRSN)
Security and Auditing - Understanding privileges and authorities
- Protect access to DB2 and its objects
- Audit DB2 activity and resources and identify primary audit techniques
- Identify and respond appropriately to symptoms from trace output or error messages that signify security problems
Performance - Plan for performance monitoring by setting up and running monitoring procedures (continuous, detailed, periodic, exception)
- Analyze performance (manage and tune CPU requirements, memory, I/O, locks, response time, index and table compression)
- Analyze and respond to RUNSTATS statistics analysis (real-time, batch, catalog queries, reports, histograms)
- Determine when and how to perform REBIND (APCOMPARE and APREUSE)
- Describe DB2 interaction with WLM (distributed, stored procedures, user-defined functions, RRS)
- Interpret traces (statistics, accounting, performance) & explain the performance impact of different DB2 traces
- Identify and respond to critical performance metrics (excessive I/O wait times, lock-latch waits and CPU waits; deadlocks, timeouts, RID failures)
- Review and tune SQL (access paths, EXPLAIN tables, awareness of query transformation and predicate processing, use of Virtual Indexes)
- Dynamic SQL Performance (DSN_STATEMENT_CACHE_TABLE, parameter markers, literal replacement, REOPT)
- Design features for performance (hash row access, inline LOBs)
- Knowledge of controlling access paths (SYSSTATSFEEDBACK table, SYSQUERY)
Installation and Migration / Upgrade - Knowledge and understanding of the critical ZPARMs (database-, object- and application-oriented, application compatibility - no DDF)
- Identify and explain Datasharing components and commands
- Knowledge of pre-migration checklists
- Knowledge of catalog and directory (new tables, change tables, new objects)
Additional Database Functionality - Knowledge of SQL constructs (temporal, archive, table functions, built-in scalar functions, recursive, common table expresssions)
- Knowledge of SQL/PL (Array data type, new array data type functions, functions and procedures)
- Knowledge of SQL/XML (results database, XML functions, cross loader with XML, xpath expressions, FLWOR, pattern matching and regular expressions)
- Knowledge of Stored Procedures (native, external, autonomous, ziip considerations)
- Knowledge of User-defined functions (scalar functions, table functions, SQL/external functions)
- Knowledge of global variables (in stored procedures, in SQL/PL, distributed considerations)
Distributed Access - Implementing distributed data access (communications database)
- Knowledge of ZPARMs (for DDF)
- Knowledge of DDF setup (DB2 Connect, Client, Drivers, profile tables, RLMT)
- Understanding and implementing distributed data access (perf settings for DDF access)
